Electricity only, moved from People’s energy to British Gas. 4 bed bungalow with oil CH and oil HW. Not a huge difference in usage summer to winter. We are in credit (only by £30) but still clearly keep up at £170 per month, and submit readings every month. They can’t explain why the increase, and when they calculated again over the phone offered £214 per month. I’ve opted for a variable direct debit so just pay for what we use, but then we get charged 5% more, for not committing to a fixed direct debit. This all seems so random. Where did the £359 suddenly come from? Thinking of looking at Octopus as others have mentioned. And no, can’t have a smart meter as rural and mobile signal not reliable. Argh, why are all these companies so dishonest?
